[xml] xmllint as an external program

[Justin Fletcher <justin fletcher ntlworld com>]

Hiya,

It struck me that xmllint is not really an internal part of libxml, and
consequently should not include libxml.h. That is, everything that xmllint
does should be capable using the external interface.

The following little patch appears to enforce this view. At least from where
I'm sitting. It's possible that xmllint relies on other internals, but no
warnings are thrown about unknown functions here anyhow.
